I often wonder if there would be a market for a high quality semi-permanent tattoo available, that could be easily removed. (or change color, or be made permanent)
I've spoken to a lot of people who cover up their "tatts" because they are embarrassed by them, (particularly women) and some of them tell me how they were never that keen on them from day one, because they didn't really want them in the first place, or they didn't look as good as they'd hoped, or that part of their life (boyfriend/girlfriend) was over etc etc.
I'm sure there must be the technology out there to develop a tattoo ink that can be made to go transluscent, or even change color, or status from temporary to permanent? I better get out my chemistry set, there might be a buck to be made! Cheers, Terry.
